ADHESIVE COMPOUND.

Specification of Letters Patent.

Application filed February 13, 1913. Serial No. 748,257.

To all whom it may concern:

' Be it known that I, VICTOR XICQVIQH, a citizen of the United States, and resident of the city of Seattle, in the county'of King and State of Washington, have invented certain new and useful Improvements in ing its adhesiveness.

Adhesive Compounds, of which the following is a specification;

My invention relates to cements,and Iconsists of an improved cement which 1s especially adapted'for securing fabrics, such, for instance as linoleum, to metal surfaces.

My invention comprises the cement made in essentially the proportions and of the in-,

gredients combined in the manner herein set forth.

The objectof my invention is to produce a superior cement for the class of uses mentioned, which shall be of reasonable cost and effective in holding the materials joined thereby, and particularly one which will be able to stand higher temperatures before los- In compounding my cement I make use of the following ingredients in the propor tions and compounded in the manner stated. Of copal varnish I take six parts and rosin three parts, which. I first combine by heating, until the mass becomes fluid. After this mixture has cooled I add two and one half (2%) parts of copal varnish and stir well. I then heat the mass and add five parts of Portland cement, this being well stirred in. The better the grade of copal which'is used in making the varnish, the bet ter is the quality of the cement made there from; The quality of the copal which appears to be most important, is its high fusing point as compared with other-resinous gums.

' The cement so made will remain soft for a considerable length of time if-kept in a mass. When it is to be used, it is spread upon the surfaces to be joined, in such thickness as will form an appreciable layerjnd one which willinsure filling all depressions in the bodies to be joined. Pressure should be applied to hold these bodies together for a considerable time, preferably from one "to two weeks.

In using this cement it is not necessary to heat up the materials to be cemented together, but the cement may be applied to cold surfaces and be; itself cold. Toloosen onld be heat parts of rosin by the application of heat until the mass becomes fluid, then adding to this, after cooling, an additional two and a half parts of copal varnish and five parts of Portland cement.

In testimony whereof l have hereunto affixed my signature at Seattle, Washington, this 7th day of February, 1913.

. VICTOR XICOVICH.
